The MOB+ kill switch from Fell Marine can stop the engines wirelessly if someone falls overboard. The xFob transmitter is designed to wear as a wristband, in your pocket or clipped to a life jacket. Unlike a standard kill-switch tether, you can move about the boat freely. If the connection with the permanently installed xHub is interrupted because a crew member falls overboard, the engines stop instantly. The engines can be restarted after six seconds. Starting at $199.99; fellmarine.com
